Construct an AP4_Sample referencing a data stream.
- Parameters:
-
data_stream The byte stream that contains the sample data. The sample object added to the track will keep a reference to that byte stream offset Position of the first byte of sample data within the stream size Size in bytes of the sample data description_index Index of the sample description that applies to this sample dts Decoding timestamp of the sample cts_delta Difference between the CTS (composition/display timestamp) and the DTS (decoding timestamp), in the timescale of the media. sync_flag Boolean flag indicating whether this is a sync sample or not
